Keywords:

• Simulation: A simulation is the imitation of the operation of a real-world process or system over time. Simulations require the use of models, the model represents the key characteristics or behaviors of the selected system or process, whereas the simulation represents the evolution of the model over time. Simulation can be used to show the eventual real effects of alternative conditions and courses of action. Simulation is also used when the real system cannot be engaged, because it may not be accessible, or it may be dangerous or unacceptable to engage, or it is being designed but not yet built, or it may simply not exist.
• Social learning: Social learning is defined as learning through the observation of other people's behaviors. It is a process of social change in which people learn from each other in ways that can benefit wider social-ecological systems.
• Generalization: Generalization, in psychology, is the tendency to respond in the same way to different but similar stimuli. For example, a dog conditioned to salivate to a tone of a particular pitch and loudness will also salivate with considerable regularity in response to tones of higher and lower pitch.

Conclusion: Simulation, social learning, and generalization are similar concepts, in which imitation is done in different situations. In the simulation, imitation of real-world activity is done by the use of some models, in social learning imitation of behavior is done by observing others, and in generalization, the response is given in the same way to different but similar stimuli. Here, the child is learning by observing the models in the fashion show, which is a kind of social learning. Hence, option (3) is correct.
